Abstract: PURPOSE: A solenoid valve for an anti-lock brake system is provided to vary the flux of oil upon slip brake. CONSTITUTION: When the increase of a brake force is demanded as the temporary increase of friction force of the surface in a slip control state, a plunger(140) is increased in a state that a piston(200) is fixed so that a fixing orifice(320) is opened. The compressed oil flowed in an entrance channel(300) passes through the fixing orifice(320) and a variable orifice(340) and is transmitted to a wheel cylinder via an exit channel(310). The slip is regulated with a brake force demanded in the wheel cylinder by the decompression reaction of the variable orifice and the opening/closing action of the plunger. In this state, when the brake pressure of a master cylinder is released, the oil is sent to the entrance channel through a gap between a bore(101) of a modulator(100) and a piston and a slot(161). Thereby, the brake force is quickly released.
